To all whom it may concern:

Be it known that I, PERLEY L. KIMBALL, a citizen of the United States ofAmerica, residing at Bellows Falls, in the county of Windham and Stateof Vermont, have invented certain new andusefulImprovements inCentrifugal Oream-Separatormiof. which the following is a specification.I

The Object of the invention is to produce a IO device of the classspecified having features of novelty and advantage. n

My invention comprehends the use of stifizo ening-bands for the innerliners, by means of which they are firmly positioned when the machine isin operation.

0. denotes the outer liner. a denotes the stiifeningband, secured to theupper end thereof. This band is split, as atcfi. The

lower end of this liner is cupped or'recessefd,

as at a, for the purpose'hereinafter mentioned.

bands on both liners.

As shown in Fig. 5, the outer liner has a pintle a which positions thebottom of the liner in the bottom of the bowl 0. The upper end of theliner is positioned by the band a bearingagainst the inner'wall of thebowl. 0 The inner liner is supported at its top in the cover d, the bandI) engaging the inner walls of the recess in the cover. The band b atthe lower. end of the inner liner is of such size that it fits snuglyWithin the recess a in the bottom of the outer liner.

The liners themselves are made of light ma- .by LettersPatent, is- 7I 1. "In a centrifugal separator the combination with the bowl, of oneormore liners, and one or more split bands secured to said liners,
